L322 Range Rover System Description and Operation
LIGHTING
86-2-30 DESCRIPTION AND OPERATION
Headlamp Delay
The LCM controls a headlamp delay function which illuminates the driveway after leaving the vehicle. The headlamp
delay will operate on dipped beam headlamps only regardless of the position of the column stalk switch.
The delay is operated when the ignition is switched off and the key removed with the headlamps switched on. The
message centre displays a 'HEADLIGHTS ON' message accompanied by a chime from the sounder. When the light
control switch is moved to the 'off' position, the message centre displays a 'HEADLIGHT DELAY' message and the
dip beam headlamps are activated for a period of approximately 45 seconds. After the delay period, the LCM
automatically switches off the delay function, extinguishing the headlamps.
Instrument Pack Warning Lamp Illumination
The warning lamps in the instrument pack for left and right direction indicator, front and rear fog lamps and headlamp
main beam are activated by the LCM via messages to the instrument pack on the I Bus. The synchronisation of the
indicator warning lamps with the external lamp frequency is controlled by a cyclic transmission of the light status on
the I Bus.
